Options
- A. Fe _2 O _3+ CO 2 FeO + CO _2
- B. FeO + CO Fe + CO _2
- C. C + CO _2 2 CO
- D. CaO + SiO _2 CaSiO _3
Answer
A. Fe _2 O _3+ CO 2 FeO + CO _2
Step-by-step solution
At 900-1500 ~K (higher temperature range in the blast furnace) Reaction which take place are: C + CO _2 2 CO FeO + CO Fe + CO _2 CaO + SiO _2 CaSiO _3 (Slag formation) Fe _2 O _3+ CO 2 FeO + CO _2 at 500-800 ~K
